A Supplement to the Common Guidelines for Education Research and Development

CADRE, the Community for Advancing Discovery Research in Education (CADRE), the resource center for the National Science Foundations' Discovery Research PreK-12 (DRK-12) Program.

Beginning in 2009, the ITEST resource centers (LRC and STELAR) asked active ITEST projects to report their use of externally developed and reliable instruments to collect data on their project outcomes.

The STELAR website now houses a database of instruments. All of the instruments listed were used to some extent by at least one ITEST project. The ITEST project is listed under the "Related Projects" heading on the instrument's page. Only instruments that could be located online are included in the database.

DLESE's mission is to improve the quality, quantity, and efficiency of teaching and learning about the Earth System, by developing, managing, and providing access to high-quality educational resources and supporting services through a community-based, distributed digital library. Intended users include students, educators and citizens of all ages, in both formal and informal learning environments.

The Library contains uniquely interactive, web-based virtual manipulatives or concept tutorials, mostly in the form of Java applets, for mathematics instruction (K-8 emphasis). The ultimate goal of the library is to create a national resource from which teachers may freely draw to enrich their mathematics classrooms. The materials is also intended to be of importance for the mathematical training of both in-service and pre-service elementary teachers.

The EdITLib Digital Library is an online resource of peer-reviewed and published international journal articles and proceedings papers on the latest research, developments, and applications related to all aspects of Educational Technology and E-Learning.

NSDL is a digital library of exemplary resource collections and services, organized in support of science education at all levels. Starting with a partnership of NSDL-funded projects, NSDL is emerging as a center of innovation in digital libraries as applied to education, and a community center for groups focused on digital-library-enabled science education. Mission: NSDL provides educational resources for science, technology, engineering and mathematics education.

The Gender & Science Digital Library (GSDL) is a cutting-edge, collaborative project between the Gender & Diversities Institute at Education Development Center, Inc (EDC) and the Eisenhower National Clearinghouse (ENC) at Ohio State University. It is funded by the National Science Foundation (NSF).
